The above list is a partial list of the many alloys we can chemical etch, call or email us to discuss metals not listed.

Metal Alloy Temper

Most metal alloys that Fotofab can use with the chemical etching process are available with different tempers. These tempers determine some physical properties of the metal. The physical requirements of your part will dictate the temper of the metal you decide to use.

Metal Thickness

Fotofab can produce your part with photo chemical machining from sheets of metal ranging in thickness from .0005 inch (0.013 mm) up to .090 inch (2.286 mm). Metal thickness tolerance often varies with the metal thickness; generally, the thicker the metal, the larger the thickness tolerance associated with it.

Fotofab stocks a wide selection of metals with various tempers and thicknesses. It is likely that we can meet your metal requirements from our stock. Our formal Lot Control Program allows us to trace each of your parts back to its certified metal source.

Fotofab metallurgists are available to help you select the most appropriate metal for your application. From etching aluminum to zirconium, Fotofab has the tools to get the job done.
